T0 all whom it mcy conc-6m:

v'Be it known that L'FREDERIO W. C

SCHN1EWIND,-a citizen of the United Statesf of America, residing' in theclty, county', and State of New York, have invented a' certain new anduseful Improvement in Coke-Oven- Discharging Apparatus, of which thefollowing is a true and exact description, refv erence being had to theaccompanying drawings, which form a part thereof.

' The present invention relates toapparatus for removing coke from theretorts or ook# .ing chambers of coke oven structures, and4J forreceiving and discharging` the coke-rei; moved from theretorts to areceiving sta- '5- tion, where the coke is discharged either. into carsfor railway transportation or into "other storing devices. f

The object of-the present inventionis to;

provide apparatus so constructed and arranged that the"cke from eachVretort can be readily and easily. transferredV to ajsuitable cokevreceiver without 'undue jarring of the 'coke andv in a gradual'manner sothat .the coke will neither jam in the retorty being emptied or bebroken up, thus avoiding inv to the oven Walls and unduecrumbling of thecoke, with aL consequent material reduction in the amount of coke breezeo r.

waste coke-dust formed. j

The bottom wall of each retort is formed end of a retort, land -ispreferably lined with- ;irebriclr C2 to shield it and the adjacentiioorbeams A2 from the heat of the glowing coke when the retort is beingemptied. The doors or' bottom, walls B are normally held in 'place bybolts or rackbars B4L operated bypinions B5 and engaging ears formed onstiffening yokes B6 secured to the members B2.

The understiucture A4 1s provided at i different levels with vrails D',E, and F',l on

which run the movable lids or coke Acover carriagesl) A and D B, andcoke receiverv carriage E, and bottom door lift carriage Frespectively.r Thecoke receiver carriage E vcomprises wheels E2 runningon the rails E journaled in boxes Ev3 on which rest the end .beams E4supporting the body E5 of the /carriage E. The wheels E2 are driventhrough gears E5 upon .cross shafts E8 which are vin turn drlvenrfromthe sha-ft E5 ofthemotor E13 'secured to the under side of the carriagebottom, the driving connection being formed of pairs of worm wheels E1oand gear wheel E11 inclosed in Vcasing E12. On the body .portion E5 ismounted the coke receiving platform proper G. The

platform Gr` is hinge connected to the platform E5 .at both-side edgesto tilt relative thereto about Vone or, the other. of two axes located"one above each fail E.V This arrangement permits lcoke to be dischargedfrom the receiver into cars located at either side of the carriageon-tracks H as shown in Fig; 3. The-hinge connections may be formed bypairs of bearings E14 formed on the -body E5, lv'each supporting a shaftor pintle E15 which is engaged by open ended bearing' members G securedto the under side of the platform G at itsopposite side edges. f EarsG11 are provided at-the side edges ofthe platform G, those at one edgeor ythe other being engaged by suitable hoistking mechanism located atthe end ofthe batteryto tilttheplatform about the pintles E15 at theopposite edge of the platform when it 1s desired to discharge the cokeinto the ,Coke

'receiving car or other receptacle located at one side or the other ofthe track rails H,

Y to receive the upper flanged edges of a pair of beams`G2,'as shownclearly in Fig. 2. At each -end of the *platform G is located aninclined and preferably removable end portion G5, which comprisesinclined beams G7 supported at their outer ends on saddle members GDresting on the transverse I-beams JGS, and

having their inner ends directly supported\ by the body of the platformG. On -the rails or beams G6 are secured platform bars G5, like thosesecured' on. the beams G2. The outer ends of the beams G are faced byend members G1".

lVith the constriftio'iiirshpwii vit will be observed that abrokencrinjured platform bar .G3 may be readily removed by sliding out the otherbars G2 at one side of it which engage the same pair of beams G2 or G7.Preferably to facilitate the removal of the bars G3 the end portions G5are secured to the body portion of the platform by readily detachable4.connect-ions,A not shown. The carriage E'propervm'ay be protected from,Water employed in quenching by a floor or covering between theAplatform E and the bars G7 if thought necessary.

' vThe mechanismfor dropping and raising vmountedal vertically movablehoisting shaft F5, having its lower 4end threaded and carrying at itsupper end a` head F'7 adapted to engage the. door; The heads FG of thetwo hoisting devices shown are connected by bars F7 which preventrotation ofthe shafts F5. l/Vithin casing F2 is located a nut for thecorresponding shaft F 5, the nut having'y i a thrust bearing F10.YVithin each casing also is located a worm gear meshing with the teethformed on the nut FK The worms F 11 ai'e carried by the shaft F12 whichmay be geared to,.or, as shown, may be the shaft of motor F5. f

In the construction shown in Figs. 1 and 'EZ the carriages E and F areentirely independent. As it is .desirable however that each door B bedropped to a definite level,

viz: that on whichthe upper edge of the `door is flush with the upperends of the inclined platformV portions G5, an arrangement maybeemployed with advantage in which the door is dropped down on to theplatform E. Such an arrangement is shown `1n Fig. 4, where the beamsE4of the carriage ,Ehre extended to form supports on whichr the doorl Bmay be dropped by the hoisting device FW As it is desirable that thecarriages E and F shouldk move together during certain stages of thedischarging o eration,'an arrangement'may be employe` for detachablycoupling the Atwoearriages to-v gether. In the arrangement .for thispurose shown in Fiffg'f the carria e E -is`ro- P s P Y i vided'withdownwardlyxtending arms or brackets E16, .which of course should be so narrangedas to clear the hoisting mechanism, and the carriage F 1s.rovided with similar upwardly lextending rackets F13, which, when thetwo carriages are in the position in'which they should be coupledtogether,` are located immediately ybeneath the brackets E1 so that thetwo carriagesmay be secured together by thefpin E11 passing throughsuitable apertures formed in the brackets E1 and F13.

' The means for covering the coke on the platform.- Gr and thereby-protecting the under oven structure proper from the heat of the cokecomprise, one or more lids or covers in the form of carriages ruiming onthe track rails D.k In -the\ arrangement shown in the drawings there aretwo of these covers D A and D B employed in discharging each. retort.Each of these carnages, which may both be identical in construction, haswheels D2 running 'on Vthe track rails D. .The body ofthe carriage isprovided at its under side with a series of I beams running parallel tothe rails D.

The I beams D11. support plates D3, which may be similar to the platformbars G3, thus forming the lid or cover proper for the glowing coke. ToAprotect the carriages proper against the heat conducted from the facesD3, which are preferably made of castl iron, a suitable non-conductinmaterial like mineral wool may be packed a ove the faces of thebars`D3.. -To prevent the coke from spilling off the sides of thereceiver` and also to protect-the adjacent portions of the Asup- Iporting structure A1 each side edgefnf each I cover is providedA withanapron or depend-4 ing shield. This apron or shield is formed bv" metalieces D which are rovided at their upper ends with grooves receiving thebase of the side I beams DH. For the purpose of connecting carriages A DB to the carriage E, the body portion of the latter may be provided withposts E13 arranged in the same vertical planes withv posts orV bracketsD3 depending from the sides of the cover carriages. By this arrangementthe 'corresponding posts D and E13 may. be4

readily connected iis-by ia'ipin D1.1 or the like.. In discharging eachretort A,the carthe drawings, the carriages D-A' and D B are provided attheir ends with depending guides D1. Adjacent guides D7 of the twocarriages employed thusunite to form a chute through which the cokepasses. With the apparatus operating as shown in Fig. 1, 2 1t is ofcourse necessary to hold the left hand cover carriage D A stationary in'order to prevent its being displaced by the thrust ,ofy

the coke as the carriage E moves to the left.

The carriage-mayof course be held stationvary in any lsuitable manner asby locking it to the track rails D .or to the overhead ovenbeams A3.l Itis also desirable in somecases to regulatethemovement of thecoke on to.the receiving platform. This may be obtainedl by'providing anarrangement whereby the guides D7, may serve inv eect. as

clamping jaws, 'and' be moved relatively to each other in order to clampand release the coke cake. For the purpose of holdingl the carriages D Aand D B stationary and of adjusting them as desired, as `well as for thepurpose of obtaining 'the clamping ac-4 tion referred to between theguides D", the

arrangement shown particularly in Figs. 5

and 6 may be employed, although it will be understood that the mechanismshown in these figures is merely. illustrative of one of manyarrangements which may be employed. In the construction shown best inFigs.

5f and .6, each cover carriage D A or D ,B

is provided at itslside between the wheels' D2 `-with spur gears D15which mesh rack bars D3 secured to the overhead oven. beams yA3, andextending parallel tothe rails D.

Each spur gear D13 has a shaft carrying at its inner end a clutch memberD-9 which cooperates with a clutch lmember D10' carried by a shaft D11.The shaft D11 is, by motor lio D13, driven through the spiral gear D13carried 'by the shaft D11 on a worm wheel on the shaftof'the motor.

Then the clutch members D9 and D10 are released, theV spur gear D15v isfree to rotate lizo .I

when the carriageD A or -DB is moved on the track D and does notinterfere with the movement of the carriage. Vhen, however,

`the clutch members p? and D1 are locked together the carriage iseffectively locked.

to the stationary oven structure through the spiral and 4worm gearconnections to .the motor D13. Such movements of the carriagev ments bythe coke receiver carriage.

as is necessary in adjusting the position of the carriage andparticularly for obtaining the clamping action between the guides D7 ofadjacent' cover carriages may be obtained by operating motors D13. Itwill of course be understood that the motors D13-may be used to propelthe carriages D A and D B along the entire length of the track formed byrails D if desired, but this is not the primary purpose of the motors inthe particular construction illustrated, since, the cover carriages maybe given large move- The clutch members D9 and Dlo vmay be controlled inany suitable manner, for instance, they. may unite With suitableelectrical connections to form an electro magnetic clutch.

It will be understood that the rails D', E and F yall extend at least tothe end 'of the battery to Which they belong, and that the rails Dextend beyond the battery., and that a suitable quenching apparatus islocated beyond `the end of'the battery for spraying `Water on the cokeand cooling it before discharging it from the coke receiver into thecars or other lcoke receptacles.

Each retort may be discharged asl follows The cover carriages D, thecoke .receiver y carriage E, and the door opera-ting carriage lEand thecarriage F are then moved slow y and gradually to the lft to allow' thecoke to descend on tothe cokeplatform GrA of the carriage E. On -accountofthe gradual up- Ward inclinationkof the advancing end G6 of `thereceiver platform, the coke cake may be transferred With 'little or nocrumbling from the top of door B to the body of the platform Gr'.Further `advancing movement of `the platform G on account of the greaterfriction on the horizontal portion of the platform causes the lower endof the cake to break up butin relatively large pieces.

The descent of the coke and thereby the manner in.\vhich it is broken upmay be regulated as before described by the adjustable, clamping actionexerted on the coked rake by the guides D7. To increase the frictionbetween the guides and the coke the forium' may be roughened asindicated at -`pled to the carriage E.

D X in Fig. 4:. When the coke from `the retort being discharged has allbeen placed upon the coke receiving platform the carriage E is moved totheleft.- as is also the ycarriage F, which has preferably been cou' Thecarriages E and F arethen uncoupled and the clutches are operated torelease cover carriages D, and the left hand cover carriage D is movedto the left to get it outofthe road; at the same time the right handcover carriage D is coupled to the carriage E as by the couplingconnection D6. After the door B and carriage F are disengaged from thecarriage E the latter is moved to the right to the quenching stationlocated at the end of the battery,`and the hoisting apparatus on thecarriage F returns the door to the normal position-Where it is securedby the-bolts B4. If, as may be desirable to obtain the necessaryclearance, the tracks D do not. extend beyond the end of the battery,the right hand cover D B Will be disengaged from the carriage E when`the former arrives at the end of the battery, and the coke carriagewill then be moved on to the quenching station, where after the coke isquenched it is discharged either into the right hand car or the lefthand car as .desired by the chains H of the stationary hoistingmechanism, not

shown, which engages the ears G11 at the left or right handedgevrespectively of the platform Gr.

Aprons or guides H2 are provided for insuring that .the coke reaches thecars. Vhen the guides H2 are suitably perforated rthey serve as sievespermitting the coke -breeze to .drop through them. It will of course beunderstood that Where there are more than one battery or unitary cokeoven structures'in a single plant, the hoisting and receiver tracks maybe .extended to permit the'receiver and hoist to operate under all thebatteries.y The tracks for the covers may also 'be so extended though incase of such extension some modification would be necessary as otherwisethe cover tracks would interfere with the operation of dischargingbetweenv the batteries. It will be observed that With the apparatusdisclosed the varihighly advantageous in its'general operation.y All ofthe devices employed are located on one side beneath the furnace wheretheir operation can be observed and conl View of the present state ofthe arl of controlling motors from a distance. Because of theseconditions the labor cost of dis- 'charging the furnaces is reduced to aminimum, the operator or operators work under favorable conditions andare notexposed to oppressive temperatures and the various devices areproperly timed.
